Things I liked:This thing works great. I like being able to have my pellets ready to go as soon as I open the lid... slowly and carefully.Things I would have changed:A lower price would be nice. Of course, I feel that way about just about everything.What others should know:At 10 meter matches we shoot 3 sets of 20 shots. I placed narrow strips of thin transparent tape over rows 3, 6, and 9. This forces the box to fill rows 1-2, 4-5, and 7-8 with sets of 20 pellets each and leaves row 10 for sighters. Makes it a bit easier to keep track of shots.

Things I liked:I needed the compensator/muzzle brake/weight for the conversion of a Crosman 2300KT into an entry level 10 meter rifle. The compensator fits the 2300 barrel perfectly. Instead of the sight that came with it I will be using the AirForce Front Target Sight (AFU1058 [PY-A-2238]) which offers more adjustment and 3 transparent sight inserts.
Things I would have changed:Sell the compensator separately. Ten dollars would seem to be a reasonable price for it. Also, the compensator should be cast with a flat spot above the mounting grooves. Additionally, the web page for the product does not make it clear that the compensator does come with the sight.
What others should know:The compensator and the sight arrive unattached. Neither the Daisy globe sight that comes with the compensator nor the AirForce front target sight will fit securely onto the compensator as is. You will need to either file the sight mounts to fit the round shape of the compensator or file a flat spot onto the top of the compensators sight mounting grooves. Also note that some rear sights cannot be adjusted high enough to work with either sight. I am using the Air Venturi Rear Sight (AA-6213147R [PY-A-3191] mounted on top of the BKL 3/8" or 11mm Dovetail Riser, 1-5/8" Long, Silver (BKL-172S [PY-A-2879]) and the combination of these parts makes for an excellent sight setup on the Crosman 2300KT.
Gets a bit spendy but some of us 2300/2400 fans just can’t seem to control ourselves.
